xpath reference is possibly outdated

Hello

in xacml 2.0 spec in "A3.15 XPath-based functions" we have:

======

4915 • urn:oasis:names:tc:xacml:1.0:function:xpath-node-equal

4916 This function SHALL take two "http://www.w3.org/2001/XMLSchema#string" arguments,

4917 which SHALL be interpreted as XPath expressions, and SHALL return an

4918 "http://www.w3.org/2001/XMLSchema#boolean". The function SHALL return "True" if any

4919 of the XML nodes in the node-set matched by the first argument equals, according to the

4920 "op:node-equal" function [XF Section 13.1.6], any of the XML nodes in the node-set

4921 matched by the second argument.

=====

,where XF refers to:

3973 [XF] XQuery 1.0 and XPath 2.0 Functions and Operators, W3C Working Draft

3974 16 August 2002. Available at: http://www.w3.org/TR/2002/WD-xquery

3975 operators-20020816

First of all, there's a fresh version of the document,
http://www.w3.org/TR/2005/WD-xpath-functions-20050915. It's dates as of
Sep 15 2005. Second, there's no "op:node-equal" function in the current
XF document.

thanks,
